I'm 27 weeks and 4 days pregnant, and i'm feeling tired mostly always, i have two smaller children too,but i'm tired most time is it normal ?

2 small kids + P.G.: I hope you are taking your prenatal iron pill daily and getting some help with those other 2 children. Of course if this pregnancy is O.K thus far by your OB, well if you WEREN'T tired I would have been surprised. So yes, it is normal.

Yeppers: Total bummer trying to be a mom with 2 little ones and one on the way. When you're pregnant, your blood volume increases, so the serum to red blood cell ratio drops a little. Translation: a functional anemia. You might have sleep apnea as well if you are overweight on top of being pregnant. What is your Mallampati score (look up diagram) & do you snore? Get a sleep study. CPAP may help.
